Groundwater Availability Modeling Section

its groundwater management plan, groundwater conservation districts shall use groundwater availability modeling information provided by the Executive Administrator of the Texas Water Development Board in conjunction with any available site-specific information provided by the district for review and comment to the Executive Administrator. Information derived from groundwater availability models that shall be included in the groundwater management plan includes: the annual amount of recharge from precipitation to the groundwater resources within the district, if any; for each aquifer within the district, the annual volume of water that discharges from the aquifer to springs and any surface water bodies, including lakes, streams, and rivers; and the annual volume of flow into and out of the district within each aquifer and between aquifers in the district. The purpose of this report is to provide Part 2 of a two-part package of information from the Texas Water Development Board to Panhandle Groundwater Conservation District management plan to fulfill the requirements noted above. The groundwater management plan for Panhandle Groundwater Conservation District is due for approval by the Executive Administrator of the Texas Water Development Board before November 13, 2013. This report discusses the method, assumptions, and results from model runs using the groundwater availability models for the northern part of the Ogallala, Seymour (and Blaine), and Dockum aquifers. Tables 1 through 3 summarize the groundwater availability model data required by the statute, and Figures 1 through 3 show the are
